发明名称 アンテナ内蔵式電子時計
摘要 An electronic timepiece has a case; a time display unit housed in the case; an annular dielectric that is housed in the case and has a conductive driven element to which a specific potential is supplied; and a conductive ground plane with an annular shape that is housed in the case and supplied with ground potential. The dielectric body and the ground plane are disposed coaxially to the same center axis with the gap therebetween in the axial (z-axis) direction less than or equal to the thickness of the dielectric in the axial direction.
